Question

A New York City taxi charges $3 per ride plus an additional $0.50 per mile. Which function below shows how to calculate the total cost of a taxi ride that is x miles long?

Answer 1

ok, so if there is an additional $0.50 per mile, and you are travelling x miles, you'd need to multiply the number of miles by $0.50. comprendo? once you figure out how to write that out, the cost is $3 per ride, so just add 3 to your equation.

Answer 2

FARE(s) 3+(.50)s
where s is distance, which you call as x miles
just replace s with x if you want. but s generally means distance or displacement in math
